London buses to be powered by coffee to reduce emission

For the first time, some of London's buses will soon be powered by a biofuel made partly from waste coffee grounds.

So far, 6,000 litres of coffee-derived biodiesel has been produced, which could help power a bus for a whole year.

The biofuel is created by mixing coffee oil extracted from coffee waste with diesel, which can be added to the London bus fuel supply chain without need for modification, Shell and technology firm Bio-bean said in a joint news release on Nov 20 (Monday).

To push for its green initiatives, the city of London has increasingly turned to biofuels for its public transportation.

The average Londoner drinks 2.3 cups of coffee a day which produces over 200,000 tonnes of waste a year, much of which would otherwise end in landfill with the potential to emit 126million kg of CO2. bio-bean works to collect some of these waste coffee grounds from high street chains and factories.

On average, Londoners consume 2.3 cups of coffee a day, contributing to 200,000 tons of coffee waste over the course of a year, according to The Daily Star.

The final mix, consisting of 80 percent of diesel and 20 percent of biofuels, can reduce carbon emission from a bus journey by 10 percent to 15 percent, the AFP reported.

"It's a great example of what can be done when we start to reimagine waste as an untapped resource", Bio-bean's founder Arthur Kay said.
